Column Appender

The Column Appender takes two tables and quickly combines them by
appending the columns of the second table to the first table. It
performs a similar function to the Joiner but can be
faster for large
tables. However, it only should be used if certain preconditions are
met. For more details please read the description of the "Identical row
keys and table lengths"-option below. When in doubt, use the Joiner.
If the input tables share some column names, the offending column
names from the bottom table will be appended with "(#1)".

Options

Identical row keys and table lengths

If the row keys in both input tables exactly match (i.e. the row key
names, their order, and their number have to match) this option can
be checked in
order to allow a faster execution with less memory consumption. If the row
keys (names, order, number) don't match exactly the node execution will
fail.

If the option
is NOT checked
the result table is newly created. This might result in a longer
processing time. However, in this case the number of rows in the input tables can differ
and missing values are added accordingly. The row keys are either taken from the first table, second table, or generated entirely new (see options below).

Use row keys from FIRST table

Only available if "Identical row keys and table lengths" is not
checked. The row keys of the first input table are used. If the first table
is longer than the second table, missing values are inserted. If the
first table is shorter, the second table is truncated.

Use row keys from SECOND table

Only available if "Identical row keys and table lengths" is not
checked. The row keys of the second input table are used. If the second table
is longer than the first table, missing values are inserted. If the
second table is shorter, the first table is truncated.

Generate new row keys

Only available if "Identical row keys and table lengths" is not
checked. Row keys are newly generated. If one of the input table is longer than the other, missing values are inserted accordingly.

Input Ports

If the option "Identical row keys and table lengths" is checked: a sorted table with n rows. Otherwise a table without restrictions.

If the option "Identical row keys and table lengths" is checked: Another sorted table with n rows. Otherwise a table without restrictions.
